The present invention relates broadly to glass cutting apparatus and more particu-v larly to apparatus of this character primarily designed for use in the cutting of glass sheets into odd or irregularshapes such as, for example,automobile Windshields. 7 An, important Object of the invention is the provision of glass cutting apparatus wherein is utilized a template or pattern adapted to rest upon or be disposed above the sheet to be cut, a cutting tool being drawn along the edges of the template orpattern to out or score the sheet along the desired lines.

Another'object of the invention is thepro- 1'5 vision of an improved template or pattern ad justable in a manner whereby to efl'ect the cutting of Windshields of-various shapes and sizes and thereby tend to facilitate, simplify and otherwise improve generally the cutting operation; V 1 V u i i 3 Another object of the invention resides in the provision of such a template or pattern of the above character soconstructedthat the shape and size thereof may be readily and conveniently varied dependent uponthe shape and size of windshield desired and further wherein the desired adjustments may be effected in a practical and convenient manner.

A further object of the invention involves the provision of a template or pattern including a i frame, carrying adjustable end -members and a removable plate, said plate cooperating with the end membersto form 3 the outline of a windshieldof the desiredsize and configuration. 1 Other objects and advantages ofthe invention will become more apparent during the course ofithe'following description when taken in connection with the accompanying drawings. I In the drawings forming a part of this application and wherein like numerals areemployed to designate likeparts throughout the "same, it Fig. 1 is aplan viewof glasscutting apparatus provided by the present invention,

longitudinally extending intermediate mem- .ber 17 connectingthe'end' pieces and by the transverse members 18, The frame is of open work or cut-out formation for the'sake of. lightness, cheapness, etc. Formed at the op I posite forward corners of the templateeframe 12 are the outwardly anddiagonally projecting corner portions 19 and'20. p i

Thus, When it is desired'to secure the-plate in position, it is first fitted upon the centering pins so that the openings 49 will be brought into 'proper posi-' 7V 7 tion to receive thesecuring elements there T v 1n i r l The *cutting of automobile Wvindshields presents quite a problem for thereason that practically all 7 V i are provided with Windshields of'different shapes and sizes; this difference in shape and size being, it may be true; in some instances,

quite smallpbut neverthelessth'e 'difi'erenc'e is an important one since thejwindshields so f difi'ere'nt makes ofautoinob'iles must be 'out' exactlytothe proper; shape and size. Heretofore, it' has been proposed that a separate template, c onst'ructedjof alumi num; be prov1ded to take'care of each dlfierent size} and shape-of windshield. However, j.

'this'vvould requir'ehaving'on hand alarge number of'templates,- and sinceit has been found that these templates are'quite 'e'XP ns ve, t-Would necessitate the e penditureo-f a considerable amount of money, some of Which Wouldv be'tied up'intemplates not very fore is to provide atemplate 'adjustablesodas to take care of a large number of different shapes and sizes of windshieldsj i i v V ntion, When it o is desired to cut Windshields of 'a luniformly predetermined shape and size, a plate 4:2 ha v- QAcco'rd ing tothe prese ntinve often used. On" the other han'd,'the manufacc 'turer must; however, be prepared'to 'fill' an order for any shape and size of windshield, and the aim of the present invention there-J ing the des red le'ngth, width and contounis' first, secured to the template frame 12 in the manner above described, after which the end members 21 and 28 are adjusted to correspond theretofo r, in otherIivords, sojth'atjtheir outer'ed g'es ,4c6ai1d tf respfectively "a eas 7 "ranged at the same angle as or coinc de with end edges 4L4 and 45' of pattern late 42.

When this has beenfdoneflhe outerfedges of j the end members *al lid pattern plate vvill idefine theses a a'shape of wind'shield' to" be i but. The templateis-then raised and the glass sheet topbe c'ut'jplaced'upon the table 10, so

that: the rear longitudinal edge thereof 7 is f "butted up againsttheledge 39, The template is thenpushed. ae'wnwardiy to rest fiat upon I the sheetvand the cutting or scoring to'ol i-awn: along the edges 43 4 4, "45, ltpfand 7 {17 75 V be termed the centering pins and are received Wltllll']; openings or recesses V to cut or score the sheet along the desired lines. The glass is then broken along these scored lines to produce the windshield of the desired shape and size and'which windshield Will be provided with forwardly diverging end edges and an inwardly bowedfront edge.

When it is desired to produce Windshields of a diiferent shape and size, the plate 42 previously used is first'removed and another plate of the desired shape and size secured in place, after which the end membersare adjusted to correspond thereto. Thus, by changing the pattern plate 42 and adjusting the end members 21 and 28, it is possible to vary the length, width and configuration of the template to correspond with the shape and size of Windshield desired. I

It is desired that some means be provided for automatically raising the template a slight distance from the table upon the release thereof by the operator and for maintaining it in such position during the placing of an other sheet to be out upon the table. To ac complish this, the substantially horizontal arms 54 and 55 may be provided, said arms being arranged in spaced relation above the table and secured at their rear ends to the ledge 39 as indicated at 56. Secured to the forward ends of the arms 54: and '55 are springs 57 having their lower ends secured to the template frame 12. Since the .arms are stationary, the templatewill be pulled upwardly by the springs upon the release thereof by the operator and will be maintained in such position until again forced downwardly.

It is to be understood that the form of the invention herewith shown and described isto be taken as the preferred embodiment of the same, and that various changes in the shape,

size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claims.
